Default 427-434 Solid roller max.effort power?

I see 346 cube solid motors making 460 HP.What would a max effort bore and stroke big cube,LS6 heads,huge cam make?

600 at the wheels? What do you think? Or leave the drive train out and go flywheel HP,650-700?

An all-out racing purpose LS1 (high compression, huge cam, custom intake, etc...) should push 600+ rwhp with LS6 heads. With C5-R heads, who knows.

I've seen a solid roller 385ci put down 500 rwhp, 422ci setups making 550 rwhp, but these bigger motors are still being developed.

I kinda doubt it. I was thinking higher C/R and a custom intake.

Who'll get one first? Not me. I'm on to max effort C5Rs now. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />
